I'm surprised that no-one ever seems to mention the great advantage that Anderson power poles have over other connectors - The fact that they are genderless. You can plug connectors together without having to worry about having the correct sex plug on the end of the wire.
It saves a lot of hassle because you can plug batteries, rigs, chargers, power supplies or whatever together without having to hunt around for adaptors or sex changers.
A great advantage when out portable and need to charge a gel cell from the car battery or under emergency conditions when you don't want additional complications.
I use the bigger moulded versions which I've recovered from scrap APC UPS units. Just Pop out the connector pins, by pressing down on the spring steel retaining clips. Then drill out the crimped cable from the pins with a bench drill. Solder new wire in as required and pop the pins back in to the connector shell.
